Enhancement: add structured fact containing list of modules

[faxm0dem]

I already wrote something similar if you could have a look and tell me if you'd accept a PR in this regard. Proposed format (structured fact):

☠ facter -p kmod
["libata","sg","e1000", ... ]

Or

☠ facter -p kmod
{"nfs"=>{"size"=>188136,"used_by"=>[]},"nfs_acl"=>{"size"=>12511,"used_by"=>["nfsd"]},...}

I am also desiring a fact for all loaded modules. @faxm0dem's second example seems about right as it would generally be more convenient to test if a module is loaded via a hash lookup rather than terating across a list.

Then again we could provide functions that would abstract this fact e.g. kmod_is_loaded('openafs')

Looks like #44 should have closed this, so closing it now.
